These four (IMHO) do actually pose clear and present dangers to human health & wellbeing at scale:
* Nuclear Weapons
* Smog
* Ozone
* Global Warming / Climate Change
They were identified as risks and (except for Ozone, which was actually tackled and is improving to my knowlege) continue to be shown as risks. Or rather, by now, as actually doing harm.
On the other hand, these two here were never the big catastrophes that they were made out to be, yet were (and are!) continually overblown.
* Drugs & Crime
* Terrorism
Neither of them ever had the existential threat potential that the other group had. Not-so-incidentally, the proposed "solutions" to these problems were always...
* highly profitable for certain industries
* useful for conservative re-elections
* based in little to no fact
* often (predictably) counter-productive.
Bottom line: if we had actually put time and money into existing, working solutions to measurable, actual problems, we would have been perfectly capable to do so. We did it for Ozone, we could have done it again. We didn't.
Instead, we put countless dollars and lives into "solving" problems that were pretty much caused by their "solutions", and mostly because that was in the best interest of very few people.
If people are tired of anything, I hope/suspect that they are tired of a political/economic system that predictably ended up producing this mess.
That's part of the problem. The general public have been hearing it for decades now, and are probably just sick and tired of hearing about it. As far back as I can remember, it's been nothing but "Nuclear weapons are gonna kill us all" "Acid rain is gonna kill us all!" "Smog is gonna kill us all!" "Drugs and crime are gonna kill us all" "The ozone hole is gonna kill us all!" "Global warming is gonna kill us all!" "Terrorism is gonna kill us all" "Climate change is gonna kill us all!" Yet, here we are, still going on towards these various cliffs. I can at least put myself in the general public's shoes for a bit and empathize with their crisis fatigue. Economic crises are felt immediately--you lose your job. It's no surprise that it's politically easier to favor economics over other crises that are perpetually happening Real Soon Now.
